TYPE-WRITER CABINET.

SPECIFICATION forming part of Letters Patent No. 458,959, datedSeptember 1, 1891.

Application filed October 18, 1890. Serial No. 367,952. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK SANDER- SON, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in TypeWVriterCabinets, of which the following is a specification.

My improvement relates to that class of type-writer cabinets whichconsists of a desk with drawers for holding papers, &c., the desk beingprovided with a recess for holding a type-writer and means forprotecting the same from dust or injury when not in use. The greatobjections to ordinary cabinets for this purpose are that they arecostly, and then the mechanism for operating the parts which inclose thetype-writer is in many cases not suited to the purpose on account ofdanger to the fingers of the operator and a lack of security when in theopen position. Therefore the objects of my invention are to provide asimple combination of mechanism which is always under control of even acareless operator, is not costly, and is not liable to becomeinoperative by long use. These objects are attained by thefol]owing-described mechanism, in which-- F'igure 1 is a front elevationof the entire cabinet open, showing the position of the type-writer indotted lines. Fig. 2 is a transverse vertical section on line (I, b ofFig. 1, showing the position of the type-Writer table when open,together with the relative position of the suspension-links. Fig. 3 isthe same section as Fig. 2, except that the movable parts are in aposition to inclose the type-writer under the top of the cabinet, thetype-writer in Figs. 1 and 2 being shown in dotted lines. Fig. 4 is aperspective view of a portion of the cabinettop at the front and centerof length, showinga part cut away for a purposewhich will be explained;Fig. 5, re spectively side and edge views of the links for suspendingthe type-writer table. Fig. 6 represents,respectively, side and topviews of hinge-pin lugs, to which are hinged the links shown in Fig. 5.

Similar letters refer to like parts in all the views.

The cabinet top A has a portion I at the front, near the center oflength, removed, Fig. 4. There is a space B below the top, which extendsrearward to the back of the cabinet and downward to the floor upon whichthe cabinet stands. Near the top and at the rear of space E is ahorizontal board 0, which is stationary and is secured at the sides andrear of space B to the cabinet.

There is a broad board E, upon which the type-writer is placed, whichboard is held in proper position by means of a pair of links (I and e oneach side, links 6 being shown in Fig. 1. These links are not alike.Link (Z has two holes f, one at each end, Fig. 5, while link 6 has notonly holes h at each end, but also a hole t at about one-third itslength from the top end These holes are for pivot or hinge pins, as willbe shown.

There is a board F at the top of the cabinet, which, when in the closedposition, fills the cut-away portion I of the top A, Figs. 3 and l.

Atj is a small roller let into a slot at the edge of the beveled part7;, Figs. 2, 3, and 4-.

The periphery of this roller stands out flush with the face of the bevel7t and the top face of table A. It will be seen by reference to Figs. 2and 3 that links (Z are hinged to pins Z, which pins are secured to thecabinet near the top of the sides of the space B. The other end of links(Z are pivoted to a lug 122, (shown in Fig. 6,) which lug is secured tothe top face of the type-writer table E, one on each side. Links e havetheir top end hinged to lugs m, which are attached to the under side oftop board F, one on each side, as shown in Fig. 1. The lower end oflinks e is pivoted to hinge-pin lugs m,which are attached to the upperface of type writer table E. Links 6 are also pivoted to pins'IL,Wl1lOl1 pins are secured to the cabinet at' each side of space 13.

There is a snap-latch at G, Fig. 1, which has a handle that projectsdownward and a position near the left-hand side of type-writer table.The snap-latch has a bolt which engages notches in the left side ofspace E and holds the type-writer table E either in the open or closedposition, Figs. 2 and The top board F has a bevel at 0, Figs. 2 and 3,which bevel fits the bevel 70, Fig. 4, of the out-away portion of thecabinet-top A when board F is in the closed position, Fig. 3.

In operation, if the cabinet is closed, as

shown in Fig. 3, the snap-latch Gr, Fig. 1, is first moved from left toright, which, disengaging its bolt from the notch at the side of spaceB, permits the type-writer table to be swung downward and outward, thisaction causing link a to turn on its pivotal pin n, the lower end ofthis link turning downward and outward until it assumes the positionshown in Fig. 2. WVhile this action is performed link d swings down andoutward upon its pin land takes the position shown in Fig. 2. Both linksat and 6 being pivoted at their lower ends to the type-writer table Ecauses the table to have the motion above described and to stand in theproper position to present the type-writer ready for use. WVhile table Eis being swung into position the top board F, by the action of the topof the arm of linklever e, is moved backward, its beveled rear edge 0sliding up bevel 7c of top board A in contact also with roller j, rollerj acting to relieve the frictional contact of the two bevels, and itstop, being above the upper face of table-top A, prevents sliding board 1from forward to close the opening in table A,

thereby effectually inclosing the type-writer away from dust or injury.On account of the position in which the links d and e are suspended thetype-writer table E,with the weight of the type-writer, cannot swingfrom either its open or closed position to do any injury should thecatch-bolt which holds it slip from its notch but the table E wouldsimply swing downward, taking a position under hinge-pins n and Z, thelinks (1 and 6 assuming a vertical position.

What I claim as my invention is- 1. In a type-writer cabinet, thecombination of the links cl and c, turning upon pivotal centers at and Zon the sides of the cabinet in space E, the front link 6, having an armextending above its pivotal center, the typewriter table to which thelower ends of said links are hinged, and sliding board F, hinged to theupper end of link e and constructed to operate in the manner and for thepurpose set forth.

2; In a type-writer cabinet, links d and e, pivoted to the sides of thecabinet in space B, as described, the length of link 6 from pivotalcenter a to its pivotal center at typewriter board E being shorter thanthe dis tance between the pivotal centers of link d for the purpose ofholding type-writer board E in a horizontal position when open and in aninclined position when closed, as shown and described.

3. In a typewriter cabinet, the links cl and e, pivoted to the sides ofthe cabinet, the table E, supported by the links, a rearward-sliding topboard F, hinged to the extended arm of link 6, having its rear edge 0inclined, as shown, and fitted to fill opening I in the cabinet-top A,and rollerj, mounted in the rear edge of opening I, on which the board Fslides, all combined and operating in the manner set forth, for thepurpose of opening and closing the opening I in cabinet-top A.
